The establishment of reverse-genetics techniques to manipulate the genome of negative-strand RNA viruses has contributed enormously to a better understanding of the replication mechanisms and pathogenicity of this group of viruses. The generation of recombinant viruses bearing specific mutations in the coding and noncoding regions of their genomic RNAs now allows the functions in the replicative cycle of specific RNA regions and protein domains of these viruses to be studied. In addition, recombinant negative- strand RNA viruses can now be designed to have specific properties that make them attractive biotechnological tools.
